The XtraBars namespace contains classes implementing the XtraBars's functionality.
The classes derived from the BarItem class represent different types of toolbar items. The visual representation of each item within a toolbar or a menu is implemented via an appropriate item link class. For instance, the item link class representing the BarEditItem within a bar or menu, is implemented via the BarEditItemLink class, etc.
There are some classes representing the different collections used in the XtraBars. These collections are used to store bars and bar items within the BarManager, item links within the Bar, etc.
The enumerations (BarItemPaintStyle, BarItemBorderStyle, BarDockStyle, etc.) define the look and feel of toolbars and bar items created via the XtraBars Suite.
